Spells require precise movements and spoken incantations; they also produce visible and fantastical effects. Because of this, everyone nearby will immediately know that magic is being used, and who by — it is impossible to cast a spell furtively.
Spells marked with (rr) next to their name are offensive spells.
When you cast an offensive spell, you perform the appropriate Magic Check and the target's Magic Defense score determines the Difficulty Level. If the spell has multiple targets, it will affect each target whose Magic Defense is equal to or lower than the Result of your Magic Check (similarly to a multi attack). The spell will affect each target whose Magic Defense is equal to or lower than the total Result of your Magic Check.
If you roll a critical success on the Magic Check, the spell automatically hits all targets.
Several spells require you to calculate the potency of their effects using your High Roll (HR) — to do so, simply take the highest die you rolled on your Magic Check. The same effect will then be applied to each target.
If the same spell is cast more than once on a target, its effects will not stack — the most recent casting will replace the previous one.
Example: The spell Elemental Shroud grants Resistance to one damage type chosen among air, bolt, earth, fire, and ice. If this spell is cast on a creature granting them Resistance to fire, and is subsequently cast again on the same creature granting them Resistance to ice, the creature will only be Resistant to ice.
If two spells have identical effects but different names, they do not stack.
